Ling Jin, a useless sword slave, had his bones broken and was abandoned in the Ten Thousand Swords Pit. He awakened to the taboo "Ten Thousand Swords Crazy Demon Art" overnight, stained the sword tomb with blood, and rose up against the sky. When he was wandering around the world, he was secretly drawn by the mysterious swordswoman Bai Li and involved in the thousand-year secrets of the sword sect. The Lord Iron Throat wants to use him to make a puppet, the mute swordsman hides the book without saying anything, the red owl pretends to be benevolent and seizes the pulse, and the old sophora whispers that the soul of the sword is not dead. He is not an avenger, but a living sacrifice of the sword - when thousands of swords scream, who deserves to be respected?
